If you have a gun, and you allow yourself to be drawn into a physical confrontation, you could find your gun in the hands of your opponant.

You don't HAVE to get into a fistfight just because your adversary is apparently unarmed, even if you're the same size or bigger. Due to the limitations of most states' CCW we don't have the same force options a police officer has... no pepper spray, no ASP, no taser, often no knife... it's fists or gun.

If the drunk had continued to advance on Wild, what was he going to do? Put the gun away and duke it out with the guy, or let the guy walk up and take it from him?

At some point you have to decide to shoot even an apparently unarmed badguy... and the law has to recognize that.
